When used with the WebUI running in a GKE cluster, the users authorization roles will be automatically synchronized based upon their IAM roles in GCP. If you are not exposing the webui on a load balancer IP address, but are instead using kubectl port-forward, you should use http, localhost and 7007 for the SCHEME, HOSTNAME and PORT; otherwise, use the scheme, DNS name and port as it will be seen by your browser.
